The invention relates to the technical field of automatic driving, in particular to an automatic driving control method and device, a vehicle, a storage medium and a chip. The method comprises the following steps: acquiring an adhesion coefficient of a target pavement position; the maximum braking force of the first vehicle at the target road surface position is determined according to the adhesion coefficient; according to the road condition of the first vehicle, the safety braking distance of the first vehicle is determined; according to the maximum braking force and the safety braking distance, the vehicle speed limiting value of the first vehicle is obtained; the automatic driving speed of the first vehicle is controlled, so that the speed of the first vehicle reaching the target road position does not exceed the vehicle speed limit value. According to the technical scheme provided by the invention, the first vehicle can be prevented from slipping at the target road surface position, so that the first vehicle does not exit the automatic driving mode at the target road surface position which is easy to slip, the experience satisfaction degree of a driver for automatic/intelligent driving is improved, and the confidence of the driver for automatic/intelligent driving is increased.

    本公开涉及自动驾驶技术领域,尤其涉及一种自动驾驶控制方法、装置、车辆、存储介质及芯片。该方法包括:获取目标路面位置的附着系数;根据附着系数确定第一车辆在目标路面位置的最大制动力;根据第一车辆所处的路况,确定第一车辆的安全制动距离;根据最大制动力和安全制动距离,获取第一车辆的车速限值;控制第一车辆的自动驾驶速度,使第一车辆到达目标路面位置时的速度不超过车速限值。本公开提供的技术方案,可以避免第一车辆在目标路面位置打滑,使得第一车辆在容易打滑的目标路面位置可以不退出自动驾驶模式,提升驾驶员对自动/智能驾驶的体验满意度,增加驾驶员对自动驾驶/智能驾驶的信心。
